Class FactIDValue

java.lang.Object
  jess.Value
      jess.FactIDValue

All Implemented Interfaces:

java.io.Serializable

public class FactIDValue

extends Value

implements java.io.Serializable

Use this subclass of Value when you want to create a Value that represents a Fact.

In previous versions of Jess, fact-id's were more like integers; now they are really references to facts. As such, a fact-id must represent a valid Fact object. Call Value.javaObjectValue(jess.Context) to get the Fact object, and call Fact.getFactId() to get the fact-id as an integer. This latter manipulation will now rarely, if ever, be necessary.
